CORPORATION or NEW YORK.

SIGNAL-LANTERN.

SPECIFICATION forming part of Letters Patent No. 745,165, dated November 24,

Application niet May 26,1903. serial No. 158.772. on model.)

To @ZZ whom, it may concern;

Be it known that I, FREDERICK W. DREssEL, a citizen of the United States, residing at the borough of Manhattan, city,county, and State of New York, have invented an Improvement in Signal-Lanterns, of which the following is a specification.

My invention relates to a signal-lantern adapted for use especially'in connection with the signal-light devices of a railroad system; and the object of my invention is to be able to use either an oil or electric light with the same lantern-body, as occasion may require or circumstances dictate.

In carrying out my invention I secure on the inside of the lantern-body and adjacent to the part provided for connection to a support a plate and4 a tubular member which opens through the bottom Of the lantern. celain socket parts receiving an i-ncandescent electric lamp are connected to said plate, and the terminals of the socket are supported appreciably distant from the body of the lantern, the electric Wires entering through the tubular member to connection with the terminals. These parts are so proportioned and placed that the oil-font and burnery (but not the chimney) may remain in the lantern, the incandescent globe occupying a horizontal position directly over the burner, so that the light thereof will be in the same position as would the light of the lamp. When the incandescent globe is removed, the socket and parts are not in the way of the full use of the lamp and its chimney. y

In the drawings, Figure lis an elevation and partial section through the bottom of the lantern-body representing my invention and with the top broken away and the slide or door elevated and partly broken away. Fig. 2 is a vertical section at right angles to Fig. l through a portion of the lantern, and Fig. 3 is a horizontal section and plan through the center Of the porcelain socket parts and lantern-body.

d represents contracted top portion,

the body of the lantern, b the c the bottom portion,

ol the lenses, and e the slide or door movable vertically in slideways provided therefor, and which parts are of usual or well-known con- The lantern-body is of the form struction.

` The porprovided with a tubular part a (see Fig. 2) for connecting the lantern to a support, which support may be upon the body of a car, a switch, or a semaphore. The oil-font f and its burner f are also of usual and well-known form and adapted to be placed within the lantern through the slide or door e.

The incandescent electric bulb g and the porcelain socket part 7c are of usual or wellknown form, and said socket part is provided with termin als m fn.. I provide a curved plate h, conforming to the curved surface ofthe lantern-body, and I secure the same to the lanf tern-body upon the inner surface by screws 2, which preferably pass through the iianges of the tubular part a', the said -plate being secured to the portion of the lantern-body directly opposite the slide or door e and located slightly above the top of the burner f', and a screw connects this curved plate h and the socket part lo together for the support of said socket part and the electric bulb.

A tubular member i', occupying a vertical position and parallel with the sides-of the lantern-body, passes through the bottom c and is secured thereto and is placed in line with the center of the tubular part a", so that this tubular member comes directly beneath the porcelain socket parts. This tubular member provides for the entrance of lthe electric ,conductors l from beneath through the lantern-body, so that their ends may be connected to the socket-terminals rm 'n without in any sense coming either into close relation to or contact with the metal body of the lantern.

In Fig. 1 of the drawings an elevation is shown of the parts with theincandescent electric bulb removed. Fig. 2 shows the same in place and also serves to indicate that if absent 9o and removed from the porcelain socket parts there would be ample room forward of said socket parts for the chimney of the burner in case the lamp was employed instead of the electric bulb. It will be further noticed by reference to Figs. l and 2 that the incandescent electric bulb occupies substantially the position that would be occupied by the iiame of the lamp within the chimney if the incandescent electric bulb were absent, as the same is suiiiciently near to the center of the lenses to answer all practical purposes.

v combining into one My invention is especially advantageous in device the possibilities ot' both the oil and electric light without changing the structure in any sense and only substituting the electric bulb and chimney of the lamp for one another.

I claim as my invention- 1. The combination with the body of a lantern and the oil font and burner, of a porcelain socket part adapted to receive and hold an incandescent electric bulb, means for securing thesarne in a substantially xed condition to the side of and inside the lanternbody, adevice providing for the free entrance of the electric conductors and for maintaining the same appreciably distant from the metal body of the lantern for connection to the terminals of the socket parts.

2. The combination With the body of alantern, its oil font and burner, of a curved plate and screws for connecting the same to the innersurface of the lantern-body at a point opposite to the slide or door and slightly above the said burner, a porcelain socket part, and means for connecting the same to the aforesaid plate so that they are adapted to receive an incandescent electric bulb and hold the same in a horizontal position in about the place that would be occupied by the llame of the oil- 3o lamp, and devices providing for the entrance ofthe electric conductors appreciably distant from the metal body of the lantern for their connection to the terminals of the socket parts.

3. The combination with the body of a lantern, its oil fout and burner, of a curved plate and screws for connecting the same to the innersurface of the lantern-bodyata point opposite to the slide or doorand slightly above the said burner, a porcelain socket part,lneans for connecting the same to the aforesaid plate so that they are adapted t0 receive an incandescent electric bulb and hold the same in a horizontal position in about the place that would be occupied by the llame of the oillamp, and a tubular member passing through the bottom of the lantern and secured thereto and occupyingaposition parallel to the metal sides of the lantern and coming at its upper end adjacent to the porcelain socket part and providing for the entrance of the electric conductors therethrough and their connection tol the terminals ofthe socket parts distant from the metal body of the lantern.

Signed by me this 21st day of May, 1903.
